ZEB1, a truly mobile handheld rapid laser mapping system from 3D Laser Mapping, has been used to explore Aboriginal cave markings in South Australia. The strange markings, called finger flutings, were thought to have been left in the Koonalda Cave between about 30,000 and 10,000 years ago.
These finger flutings are the creation of hands dragged along existing grooves in soft limestone cave walls. It’s amazing they have lasted this long as the limestone is very fragile and crumbles easily at a mere touch. With the help of the ZEB1 handheld mobile mapping system, researchers have been able to create a detailed 3D Survey of the cave system. Combining this 3D survey data with high resolution photographs and analysis of the flutings, archaeologists from the SA Museum can analyze them.
If you provide a product or service, things will invariably go wrong. A deadline will be missed, the product will break, or an expectation won’t be met. It goes without saying that we must direct most of our attention toward doing what we say we will do. If we continuously miss commitments and make it hard for our customers to do business with us then we won’t be a business for long. However, how do you continue to deliver service excellence when thing go wrong? Here are a few thoughts:
Run Into the Fire
It is often tempting to avoid the conflict or dance around the issue at hand. This just makes things worse in the long run. As the service or product provider, begin the process of dousing flames of anger and disappointment with blunt truths and full disclosure. This may cause the flame to flare up temporarily, but in the long run you will build trust and have a much better chance of salvaging the relationship.
In July, Esri and MapmyIndia announced a Strategic Business Alliance that is designed to expand the use of geospatial technology in India. MapmyIndia has extensive data covering all of India’s 600,000 towns and villages, approximately 10 million points of interest and 1.9 million kilometers of highway and street network. The company plans to migrate its entire data production environment to the ArcGIS platform, so that it can take advantage of Esri’s cartographic tools and workflows. Over 80 percent of all automotive navigation systems installed in India use MapmyIndia data and the company sends out data updates every four to six months.
A career in remote sensing and GIS exists in every imaginable discipline, from environmental science to commercial businesses and much more. Such a career path has a wide range of opportunities available to let you combine your passions or interests with GIS and or remote sensing for a satisfying and successful career. Intermap’s very own Senior Project Manager, who keeps us on track with our large mapping projects where we are currently mapping the diverse landscapes in the Philippine’s and Alaska, has been in the mapping industry for the past four decades.
DigitalGlobe – a Partner’s Partner
August 19, 2013 by Steve J. Allen, Sr. Mgr. Business Development EMEA/R
Exciting times are ahead for DigitalGlobe and our partners. In the Europe, Middle East, Africa and Russia (EMEA/R) region where I work on the Business Development team, we are always on the lookout for new and exciting companies in the GIS space who can leverage our data and add value to our products and services. In order to practice what we preach and live our Purpose, Vision & Values – PVV – we have tried our best to leverage the information and insight to be gained from the millions of square kilometres our constellation of satellites collects each and every day. And our recent combination with GeoEye has helped significantly increase our fantastic collection capacity.
Often, it is our customers and partners who recognize the value of our data and help us to extract as much significance as possible out of each and every pixel collected. As a result of these engagements, we have begun to look closer to those in our GIS community who can assist us in realizing our Vision – by 2020: to be the indispensable source of information about our changing planet.
Geospatial Solutions for Natural Resources
August 19, 2013 by Mladen Stojic, President of Hexagon Geospatial
Natural resource companies face the significant challenge of successfully prospecting, evaluating, and extracting materials and resources from the earth through mining and drilling.
From mineral exploration to discovering where oil drilling may disturb critical habitats, these companies need to collect and manage massive amounts of data. Often, this data can be difficult to access, prolonging or complicating their ability to derive valuable insights for smarter decision making.
Once the appropriate data is accessed, Geoscientists use powerful algorithms and processing capabilities to perform rapid “what-if” scenarios on huge and complex datasets. In addition, with the demand for localized resources like fossil fuels, minerals, and ores on the rise, these companies need a unique set of assessment tools for enhancing efficiencies and overall effectiveness.

Ground control points (or GCPs for short) consist of a system of points for a given project area whose x, y, and z positions are known and referenced to a ground coordinate system, such as the North American Datum of 1983 (NAD 83), and whose images can be positively identified in corresponding imagery. Historically, such control was established by means of field surveys, until now. CompassData has a proven technology to provide extracted GCPs from remote sensing surveys, eliminating the need to have feet on the ground. Mr. Hayden Howard, Vice President at CompassData commented that “until recently, there has been no option for controlling an optical image in restricted areas such as China, Cuba and North Korea but with this technology we are now able to extract accurate coordinates for features that can be used to verify or control a satellite image or DEM.” CompassData’s technique has great advantages in remote and dangerous terrain. CompassData remotely sensed GCP (RSGSP) technique involves the extraction of accurate 3D RSGCPs from TerraSAR-X SpotLight and StripMap images.
They have evaluated the RSGCPs against Differential GPS control points and/or a highly accurate LiDAR DEM on varied test sites, all situated in challenging terrain and confirm accuracies to +/- <1m. Such control is ready for use in accurate georeferencing of airborne and spaceborne imagery and for the vertical and horizontal assessment of digital elevation data, to name two common applications of GCPs. Although GCPs collected by terrestrial means typically offer higher accuracies, this spaceborne approach is a significant milestone in control.
